Itistn'r obj'ectof the ihvention to provide external and readily accessible means so that the setting of the regulator can be changed quickly with ease and certainty if the necessity should arise, without moving the body or casing of the regulator and without disconnecting the hose or piping, and yet to safeguard the regulator against mischievous or malicious manipulation. A further object is to provide means for indicating outside the regulator the condition at which it is set.

The regulator comprises a tubular member adapted to be connected in a hose or other outlet from the standpipe, which outlet is ordinarily s imm ng t aa iu tabreymea e for regulatin the-flows M Fig. 2 is a cross-sectional view-- takem omthe Iine 2 -52 ef Fig1?;-

The casing 6 is formed with an interiorly threaded inlet opening 7, into which is screwed the inlet conduit 8, and with a discharge connection 9 having exterior threads 10 adapted to receive a tubular casing 11. Intermediate the inlet and discharge connections the valve has formed therein the circular valve seat 12 adapted to cooperate with the valve member 13, carried by the stem 14,.the latter being threaded in the valve bonnet 15 and passing through a stuffingbox 16 and being provided with a hand-wheel 17. Formed integral with the central portion of the casing 11, or secured therein, is a fixed disc 'i view cm the o or wall 18 having a plurality of sector ports 28 5O cut through it. This disc has a central aperture, which is preferably threaded. A disc 19, formed with similar ports 21 is fitted rotatably in the casing and lies against the fixed disc, the disc 19 being connected to the fixeddisc by a shouldered screw 20, which holds the rotatable disc in place while permitting it to be turned.

The disc 19 has teeth 22 which are engaged by the threaded part 23, or worm, of a spindle 24. The spindle 24 is rotatably mounted in a lateral extension 25 of the casing 11 and a stuifing-box 26 is provided; The outer end of the spindle has a handle 27 by means of which the spindle may be rotatedsandzthus turn thedisc 19-in relation to the fixed. 1.. .7 v

The ports 28 in the fixed disc are indicated in broken lines in Fig. 2, and it will be quite obvious from the figures that by means of the threaded.

spindle 24 the disc 19 may be rotated in 'rel a'tion to the spider 18 so as to give any flow area..desired through the ports 20 and 28.

In the form of the device.shown in.Figs. 1{2 and 3, means are illustrated for holdingthe ports in substantially any desired set relation to each o erh s: ean c mn se as n 29 V+ ine'a por ion ifienci n the ndle en e 27 i o her end sec resiii -s b t n iellyipe f manent manner by riveted zscrews or otherwise, lue 3 :exten iro :t ea n 11.; Th casting 29 is made. of abrittleor fra ilematerial and hasia weakenedportion;32,-so that a slight n w a h mm r; r the 1. ec se it to'break alongzthezweakened ;l ine, after which the'spindle can be rotated toincrease or decrease the flow area.

In this instance the regulating device is located in the discharge branch of the valve.

The fixed disc 36 has ports 37 and the rotatable disc 38 similar ports 39. The position of the disc and spider in relation to each other is reversed m: tha sh w n 1 n he; fas means 40 is slightly different, but these differences are not significant.

The disc 38 has on its lower face a segmental rack 41," which is engaged by a pinion 42. The pinion 42 is-mounted on a spindle 43, passing through a boss44 and a stuffing-box 45.

i The outer end ofthe spindle 43 has lugs 46 for a spanner wrench or for operation by hand. An

indicator 47 cooperates with an index 48 on the bossy44 so as to register the position of the disc 38. A frangible arm 29%.enga'ging oneor other of the ,lugs46 serves to loci; the re'gulator at'the' degree of port opening for whichit may. be, set at the time of installation or at any later time. s In the majorityof; instances the outlet opening ofithevalve casing 6, or'anrextension thereof, forms the most convenient location for, the device embodying the invention, and I have, shown it in this position in the illustrative aform, butit will be apparent that-thespecific location of the device 'with' respect to'--the"main valve may-Ibo varied and that in so far as the operation of the device is concerned it might be placed on the inlet side of the valve.
